Integration with WP

I’ve read the topics on this subject on the support pages, but they are about integrating the databases.

I have a WP weblog without user registration (I pubish, they read and comment, I validate)

I’d like to add to my site bbpress as some kind of support forum, so I’d like to intégrate it form a design point of view not from a database point of view (in fact I’d like to display bbpress inside WP, like a wp page or something like that).

i’ve got a full running WP. so i install bb in a directory inside WP’s means ROOT/ is WP and ROOT/bbpress is bb. bbpress worked fine when it was in it’s own database too. but when i edited the few lines… at the bottom of bbpress’ config.php, to direct to wordpress’ prefixes and urls (i also edited the top lines to direct to my wordpress database as well).
